Abstract

A power transmitting assembly having a differential case and a differential gearset that is received in an interior chamber in the differential case. The differential case defines a tubular bearing mount and a plurality of oil galleries. The tubular bearing mount terminates at a radially extending shoulder. Each oil gallery intersects the radially extending shoulder at a first end and extends through the differential case to communicate with the interior chamber. At least one location along the length of each oil gallery has a lateral cross-section that is smaller than a lateral cross-section of that oil gallery's first end.
